ALASKA VOLCANO OBSERVATORY DAILY UPDATE U.S. Geological Survey Saturday, May 26, 2018, 10:14 AM AKDT (Saturday, May 26, 2018, 18:14 UTC)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Low-level unrest continues at Cleveland volcano. Elevated surface temperatures were observed in three, high resolution satellite images over the past day. Two of the images indicated moderately elevated temperatures consistent with an open vent. A third image showed hotter temperatures and may indicate lava nearer to the surface. No activity was detected in seismic or pressure sensor data over the past day.
Cleveland volcano is monitored by only two seismic stations, which restricts AVO's ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.
The Alaska Volcano Observatory is a cooperative program of the U.S. Geological Survey, the University of Alaska Fairbanks Geophysical Institute, and the Alaska Division of Geological and Geophysical Surveys.
